Early Career
After completing his schooling, Jackson began the study of law. In 1786 he was licensed at Salisbury, N. C., and in 1788 went to Jonesboro, now in Washington County, Tenn., then in North Carolina. After a brief career at Jonesboro he received an appointment as U. S. Attorney for the Western District of North Carolina with headquarters at Nashville. He reached Nashville in 1788. He took an active part in Public Affairs and was a member of the Convention that framed the Constitution of Tennessee. In 1796, when Tennessee was admitted to the Union, he was chosen as the first Representative of the new state to Congress. A year later he was appointed to the United States Senate, and after a short service he resigned and subsequently became a member of the Superior Court of Law and Equity, holding this position until 1804, when he resigned to devote himself to personal affairs.
